To provide a method and system for optimizing power resources in wireless devices.

There is provided a device which returns to a sleep mode so as to conserve energy when no data is being sent thereto. All device destination identifiers (14) are organized and transmitted at a time. If a message listing (10) search indicates that no message is being sent for a device, the device may continue with any other activity that needs servicing, or if no other activity is pending, it may shut down to conserve power until the next wake-up period arrives. If the search returns a positive indication, the count value (12) when the identifier is found can be used to determine the location of a pointer (16) to the message.
